What is a Keyway Machining Machine?

For those involved in machining and manufacturing, the term “keyway” is likely familiar. Keyways are structures that prevent machine parts like shafts and gears from slipping. To machine these keyways, there are specialized machines known as keyway machining machines. There are various types of keyway machining machines, which I will explain below.

Types of Keyway Machining Machines
Key Slotter
A key slotter is a dedicated machine for keyway machining, also known as a slotter machine. It uses a cutter of the same width as the key and performs an up-and-down motion to cut the keyway. It can handle various workpieces and the cutters are inexpensive. Additionally, it can handle both blind keys and taper keys.

Key Seater
Unlike the key slotter, a key seater drives the cutter from top to bottom to machine the keyway, making it a highly rigid machine. Due to its high rigidity, it can finish hard-to-machine materials in a short time. However, it has the disadvantage of not being able to machine blind keys or taper keys due to its structure.

Broaching Machine
A broaching machine, which excels in gear machining, is also a type of keyway machining machine. It uses a broach cutter with multiple teeth to machine from top to bottom. It can process a large number of keyways at once, resulting in fast machining cycles and high rigidity of the cutter itself. Besides keyways, it is also used for machining internal gears and splines, making it a versatile machine for various workpieces in a short time.

Summary of Keyway Machining Machines
While machining centers and NC lathes are representative machine tools, niche and specialized machining tasks like keyway machining cannot be performed by these machines. Therefore, specialized machines like keyway machining machines are in demand and indispensable in the manufacturing industry.

Our company has experience in customizing key slotter specifications based on comb-type lathes. If you require high-precision keyway machining, please feel free to consult with us.
